Abstract

Mountainous rangelands ecosystems provide best natural habitats, biodiversity, soil and water conservation, thus their sustainable management needs information and knowledge about relationship between elements of this ecosystems. The aim of this research was study of the relationships between plant species and ENVIRONMENTAL FACTORS to determine the most important effective factor in the DISTRIBUTION of the understudy plants. For this purpose 20 land units were selected from overlaying slope, aspect and height maps using geographic information system (GIS). Within each unit was done along three 100 meter transect. 10 plots (1m2) established along each transect in 10 meter distances. Sampling method was randomized-systematic. At the beginning, a profile was dug and soil samples were taken from 0-30 centimeter in starting, mean and ending points of each transect. Soil factors such as N, P, and OM, pH, EC and texture were determined. Phytosociological data was analyzed by AFC and CAH methods using ANAPHYTO software. In this area 5 ecological groups have been distinguished. In order to investigate the relationships between plant species and ENVIRONMENTAL FACTORS MULTIVARIATE ANALYSIS was used. The results showed that the most important soil factors in establishment and DISTRIBUTION of species are N, P and texture and topographic factors are slope and elevation.
